The bush has a tapered outer diameter.

The gear has a tapered inner diameter.

Only one hole among the two holes in the bush or in the gear is tapped.

Split tapped hole in the bush align with split un-tapped hole in the gear and vice versa.

Violet screw is for releasing the gear.

Red screw is for tighting the gear.

Use two symmetrical violet screws and two symmetrical red screws to avoid eccentric clamping and releasing forces.

This mechanism is used when the angular adjustment between gear and shaft is needed.
